the blistered leaves may be nipped off with the finger 
and thumb, and burned; but where this is not practicable 
the leaves should be carefully gathered when they have 
fallen, and burned, thus preventing the winter stage from 
developing, and the fresh attack in spring. 
The leaves being the greatest sufferers, it is necessary 
to take active steps to eradicate this disease, as the food 
cannot be manufactured by them if they are badly diseased, 
and the whole tree will in consequence suffer. 
STRAWBERRY MILDEW 
This disease is not looked upon in the light it should 
be. It is generally attributed to a wet season or badly 
bedded plants, &c. But it is a disease which ought to 
be checked as much as any other plant disease. It is 
only too well known by those who grow this fruit, especially 
when it attacks the fruit itself. This, however, is not the 
first stage. It first makes its appearance in the leaves, 
where it forms a delicate white mycelium, afterwards pass- 
ing on to the fruit, where it destroys the tissue by devour- 
ing the cell contents, leaving simply a decaying mass. 
When the fruit is attacked it is the ripest that first suffers, 
but in warm, wet seasons, when the disease attains its 
greatest luxuriance, it attacks all kinds of fruit, from the 
very youngest to the fully ripe, doing enormous damage. 
When the disease has matured it begins to produce fruit. 
This is very well known, in appearance at least. Little 
branches are sent out into the atmosphere bearing conidia 
or spores; they are produced in countless numbers, and, 
of course, are blown or carried about by the wind, insects,
